NATIONAL SEMICONDUCTOR LMX2531 Manual

Update: 30 September, 2023

The LMX2531 is a low power, high performance frequency synthesizer system which includes a fully integrated delta- sigma PLL and VCO with fully integrated tank circuit. The third and fourth poles are also integrated and also adjustable. Also included are integrated ultra-low noise and high precision LDOs for the PLL and VCO which give higher supply noise immunity and also more consistent performance. When com- bined with a high quality reference oscillator, the LMX2531 generates very stable, low noise local oscillator signals for up and down conversion in wireless communication devices. The LMX2531 is a monolithic integrated circuit, fabricated in an advanced BiCMOS process. There are several different versions of this product in order to accomodate different fre- quency bands. Device programming is facilitated using a three-wire MICROWIRE Interface that can operate down to 1.8 volts. Supply voltage range is 2.8 to 3.2 Volts. The LMX2531 is available in a 36 pin 6x6x0.8 mm Lead-Free Leadless Lead-frame Package (LLP).
